Your sig image could be quite a bit bigger if you would like. I personally don't care for the big arse sig images, (clutters up the pages) and I like the size of yours as is especially if you post a lot, but if you want it bigger, I'll help you out. I'm just sayin...

BUT, If you feel that strongly about a generic topic such as that, and you want it big, let me know, and I'll hook it up.
